Abstract

Objective: Animals can develop hearing loss just like humans, so it is important to carry out tests to identify it, since animals can also suffer from tinnitus, presbycusis, ototoxicity, among others. The aim of this research is to provide a state of art regarding hearing loss and hearing assessment in animals.

Materials and methods: For this qualitative systematic review, a search was carried out with relevant keywords to search the electronic databases such as PubMed and B-on in March of 2023. The articles were submitted to inclusion and exclusion criteria and the most important data, regarding each article, are presented in an information table. The data collected and discussed from each paper was the author, year of publication, country, sample number, animal species, the equipment used and the tests carried out, and additional relevant notes.

Results: A flowchart was created following the PRISMA guidelines and 26 articles were included in the systematic review, ranging between the year 1983 and 2022. The most analyzed species were cats, monkeys, and dogs. The most common clinical conditions were sensorineural hearing loss, Noise-Induced Hearing Loss (NIHL), and tinnitus.

Conclusion: Animal studies are relevant to better understand the biological phenomena of non-induced hearing loss and we can transpose the effects/mechanisms on the same to the human species through theoretical models.
